Product overview: Fluke 771 Milliamp Process Clamp Meter

The Fluke 771 delivers all the basics. It measures 4-20 mA signals without "breaking the loop", allowing you to measure low level dc current while saving downtime and money. You can also use it to measure output signals from transmitters without breaking the loop when maintaining and troubleshooting process and automation equipment. This saves time and avoids disruption to the process. For more convenience, the detachable clamp can be attached to the wire you're testing while you move the meter—connected by the extension cable—to a better viewing position. This is especially helpful for taking readings in tight locations.

Other useful features:

Captures and displays changing measurements with Hold function

Extends battery life with auto-off and backlight timeout

Dual backlit display with both mA measurement and percent of 4 to 20 mA span

Measurement Spotlight to illuminate hard to see wires in dark enclosures

Measures 10 to 50 mA signals in older control systems using the 99.9 mA range

Automatically changes the 4 to 20 mA output for remote testing
